LED LAMP

摘要

An LED lamp includes a base, the transition insulating element connected therewith which is made of dielectric plastic with the cavity inside. The power supply is located on a PCT with the heat-conducting metal base and attached on the radiator. The radiator is made as rod-shaped section profile having side faces pointed at different directions, on which the LED modules are placed, as well as ribs extending therefrom. The radiator is within the diffuser made of plastic. The radiator has longitudinally oriented ribs located on a portion of radiator height and extending from the surface of the radiator between faces for formation of heat removal surfaces. The diffuser has a cap made as longitudinally oriented segmented shells, each located in front of LED modules of one face and covers them, isolating these LED modules from the ones on the adjacent face. Longitudinally oriented ribs are located between segmented shells.

1. An LED lamp comprising:
a base; a transition insulating element connected to the base, the transition insulating element formed of a dielectric plastic; the transition insulating element having a cavity inside it; a power supply located in the cavity, the power supply being connected to a plurality of LED modules; wherein each of the LED modules is made on a printed circuit board with the heat-conducting metal base and attached on the radiator; wherein the radiator has a central part having a rod-shaped section profile and ribs, wherein the central part includes side faces pointed at different directions, whereon the LED modules are located are on the side faces, and wherein the LED modules are placed inside the diffuser made of transparent plastic; wherein the diffuser includes outer surface sections stretched in a direction from the base and inner sections sunk between surfaces, such that the LED modules are placed on radiator faces inside the diffuser in front of the inner sections; wherein the radiator includes longitudinally oriented ribs located at least on a portion of radiator height and extending from the surface of the central part between its faces so as to form heat removal surfaces; and the diffuser functions as a cap having longitudinally oriented segmented shells having separate longitudinally oriented segmented shells, each of the shells located in front of the LED modules of one face of the central part and covers the LED modules, thereby insulating these LED modules from the LED modules on an adjacent face, and wherein the longitudinally oriented ribs are located between the shells.
